Personality Disorders – Cluster A

As mentioned in my opening post about personality disorders, personality disorders are split into three clusters: A, B, and C. This post will discuss the cluster A personality disorders. Cluster A disorders are characterized by distrust, suspiciousness, and social detachment. Often, people with cluster A personality disorders are considered eccentric or odd.

The characteristic traits of paranoid personality disorder are suspiciousness and mistrust of others, tendency to see oneself as blameless, and tendency to be on guard for perceived attacks by others. The disorder develops in early adulthood. To be diagnosed, a person must exhibit 4 or more of 7 traits: 1) he suspects, without sufficient basis, that others are exploiting, harming, or deceiving him; 2) he is preoccupied with unjustified doubts about the loyalty or trustworthiness of friends or associates; 3) he is reluctant to confide in others because of unwarranted fear that the information will be used maliciously against him; 4) he reads hidden demeaning or threatening meanings into benign remarks or events; 5) he persistently bears grudges; 6) he perceives attacks on his character or reputation that are not apparent to others and is quick to react angrily 7) he has recurrent suspicions, without justification, regarding fidelity of spouse or partner. 

Of course, I am unqualified to diagnose anyone with a personality disorder, but I think real-life stories are helpful. 

When I worked in retail, there was a guy that I had a crush on. We had been “friends” for almost a year, and I figured it was ok to tell him I liked him. He freaked out and said that I’d betrayed him (because he wasn’t ready to date anyone due to a bad experience in the past). 

He soon became incredibly paranoid. He accused me to the manager first of stalking him within the store, then of calling his phone number just to hear the sound of his voice (mind you, this guy never handed his phone number out to anyone, so he was basically accusing me of sneaking into the office and illicitly looking up his number), and finally, he accused me of placing a kilo of marijuana near his car. (Though he couldn’t produce said kilo for evidence.) 

Looking back, I realized his behavior had been odd all along. He was huge on conspiracy theory; stockpiled guns; thought everyone was out to get him; didn’t tell anyone where he lived, what his phone number was, or any personal details about his past; and he accused me of being nasty and demeaning when I made a casual comment “Oh, you’ve already started Christmas shopping? Seems a bit early.” And boy could he hold a grudge.

Since then, I’ve wondered what happened to this guy. He was really a sweet, caring person. I worry about his health and safety, since his paranoia clearly had a huge negative impact on his life. 

This is one of the personality disorders that would be abolished if the next DSM adopts a dimensional approach as discussed in my previous post. I wonder what category these traits would fall into then? 

Schizoid personality disorder is characterized by impaired social relationships and low desire to form attachments to others. To be diagnosed with schizoid personality disorder, a patient must have 4 of the following 7 traits: 1) he neither desires nor enjoys close relationships, including being part of a family; 2) he almost always chooses solitary activities; 3) he has little, if any, interest in having sexual experiences with another person; 4) he takes pleasure in few, if any, activities; 5) he lacks close friends or confidants other than first-degree relatives; 6) he appears indifferent to the praise or criticism of others; 7) he shows emotional coldness, detachment, or flattened affectivity. 

This is another personality disorder that would disappear with the dimensional approach.

People with schizotypal personality disorder are also loners. People with scizotypal personality disorder tend to have superstitious beliefs, and some experience psychotic symptoms like believing they have magical powers. They can also be paranoid, have distorted speech, or see special meaning in ordinary objects or events. Schizotypal personality disorder is thought to be related to schizophrenia – perhaps a less severe manifestation or a precursor to schizophrenia. 

In order to be diagnosed with schizotypal personality disorder, a patient must have five or more of the following traits: 1) he has ideas of reference (believing innocuous events or objects have strong personal meaning); 2) he almost always chooses solitary activities; 3) he has unusual perceptual experiences (mild hallucinations); 4) he has odd thinking and speech (e.g. vague, circumstantial, metaphorical, overelaborate, or stereotyped); 5) he exhibits suspiciousness or paranoid ideation; 6) he has inappropriate or constricted affect; 7) his behavior or appearance is odd or eccentric; 8) he has a lack of close friends or confidants other than first-degree relatives; 9) he has excessive social anxiety. 

This is the only cluster A personality disorder that would not be lost if we switched to the dimensional approach of diagnosis.

Dark Eden, by Chris Beckett

Dark Eden, by Chris Beckett; narrated by Matthew Frow, Jayne Entwistle, Ione Butler, Robert Hook, Heather Wilds, Nicholas Guy Smith, Hannah Curtis, Bruce Mann


When a group of four people have to land on an unknown planet to regroup and repair their ship, they decide to split into two groups – a man and woman who do not want to risk the flight back remain on “Eden” alone, and the two others set back off for Earth with promises to send a rescue ship as soon as possible. Generations later, the people of Eden are still waiting. Still hanging out in exactly the same crash-landing spot. Still following the matriarchal rules structured by the mother of all. But their small area is becoming too crowded. They have to forage farther and farther for food. 



John Redlantern is frustrated with “Family.” With their stubbornness at remaining in one spot when they could clearly spread out over the vast planet and have enough food for all. He’s tired of the extreme ritualistic nature of “Family.” The artifacts from planet Earth are passed around to be “ooohed” and “ahhhed” at, but they are meaningless to a people who have never experienced technology. John is tempted to disrupt the circle of the past, and create a new path for the “Family.” In doing so, he breaks down everything “Family” represents.

Let me start with an important point: although John Redlantern and his friends are teenagers, this is not a teen book. It’s “literary science fiction.” The beginning of the book, which builds the world, the people, and the tension, is really long and slow. It was a bit of a slog to get to the turning point. Once that happens they story finally begins to move a little faster – but even the post-turning-point action is slow. 

The reason the narrative is so slow is because this is a story about Meaning with a capital M, and not about plot or action. Don’t get me wrong. There’s a plot. A plot with Meaning. There were several allegories to the story. The obvious one is the Biblical creation story. It’s all about how innocence is lost when people begin to get bored. But boredom is in our nature. Without boredom, we never learn new things. And new experiences don’t just change you, they change the world. 

Dark Eden also explores a destructive nature of men – as opposed to a more structured, peaceful and confining nature of women. (This seems to be what the book implies, it’s not exactly what I think of the gender divide.)

Dark Eden demonstrates the irony that change is needed to survive, but change is destructive to survival. It’s not just a book about changing the world. It’s also about how the world changes the individual. The main characters in the book, especially John Redlantern and his lover Tina Spiketree, develop into strikingly different people as they adapt to the changing world. Innocence is replaced with deviousness. Ivory towers collapse, covering all bystanders with dust and grime. This is a story of identity.

In other ways, Dark Eden is a book about faith. How faith can lift you up and keep you strong during difficult times. But how it can be manipulated against you, as well. And how, as you realize everything you had faith in is mistaken, you are first paralyzed with numbness, but then are able to move on as a new person. 

I want to give a good review for this book with so much Meaning. I mean, it should have been good. It had Meaning. But a great book has both Meaning and an ability to fascinate even if you don’t see the Meaning. Dark Eden did not. In Dark Eden, the story was lost in the darkness because you were blinded by the bright, shiny Meaning. It was too slow, the hero wasn’t even likable if you considered him an anti-hero, and it was thoroughly uncaptivating. I totally understand why it won the Arthur C Clark award and why it comes so highly recommended. Beckett’s world was unique – colorful and dark at the same time. The setting was unsettling and realistic within the boundaries of science fiction. The lingual drift was a nice, realistic touch. But most of all, the book was slow and Meaningful.

3.5 snowflakes for unique world building and Meaning

As an afterthought – I would like to post this Twitter conversation: 

It is authors that are willing to interact with their readers, even when given a mediocre review, that are truly great. I had been on the fence about whether to read the second book in the series or not – because I am a little curious where his Meaning will go – this conversation put me over the edge to want to read it. Because when someone cares about his readers, I want to like his books more. 🙂

Personality Disorders – Clusters and Dimensions

Personality disorders are a difficult topic for me. For one thing, they are highly stigmatized. And I think the term “personality disorder” encourages that stigma by suggesting that there is something terribly wrong with a person’s identity, rather than implying that people with these disorders respond to the world in a highly ineffective manner that creates problems for themselves and others. In fact, Butcher describes “personality disorder” in his textbook Abnormal Psychology as: characterized by “chronic interpersonal difficulties and problems with one’s identity or sense of self.” This description is good as long as we accept that the “problem with one’s identity” is that one’s self-esteem and view of one’s relationships with others is unstable. 


Everybody exhibits some dysfunctional beliefs and behaviors, but they should not be diagnosed with a personality disorder unless the behavior is pervasive and inflexible, and causes “clinically significant” distress or impairment in functioning. People with personality disorders generally cause just as many problems for others as they do in their own lives. Most do not recognize the dysfunction in their own thoughts or behaviors; therefore, it is often friends, family, or the law that force people with personality disorders to seek treatment. 

Personality disorders are grouped into three clusters: 

Cluster A includes paranoid, schizoid, and schizotypal personality disorders. People with cluster A disorders tend to be suspicious, paranoid, and/or withdrawn. 

Cluster B includes histrionic, narcissistic, antisocial, and borderline personality disorders. People with these disorders have a tendency towards drama, emotionality, and erratic behavior. 

Cluster C includes avoidant, dependent, and obsessive-compulsive personality disorders. These people tend to experience anxiety and fear. 

Most personality disorders are not caused by a few traumatic events, but by a build-up of many stressors throughout life – like childhood abuse, neglect, or criminal behavior in parents. A child’s natural temperament may also have a strong impact on the development of a personality disorder later in life. 

Compared to the other mental illnesses, there is little research on personality disorders. This is because people with personality disorders often do not feel there is anything wrong with themselves, or if they realize there is something wrong, they have less-than-helpful personality characteristics (such as lack of empathy or withdrawn social interaction). Another difficulty in studying people with personality disorders is the large amount of misdiagnosing that occurs. The criteria for diagnosis are more influenced by a clinician’s judgement than are the criteria for other mental illnesses. 

Due to these difficulties in diagnosis of personality disorders, much work has been done in developing dimensional systems as an alternative to the cluster model. A dimensional model would rate a person on a set of personality traits, thus providing an overall behavioral pattern. Such an analysis would theoretically be more empirical than the cluster model. Such changes were proposed for the DSM-5, but they were deemed too complex for rushed clinicians and were shunted off into the “Emerging Measures and Models” section. 

One popular dimensional approach is the five-factor model. According to proponents of the Big Five, everyone’s personalities can be defined by our strengths and weaknesses in five traits: neuroticism, openness to experience, extraversion, agreeableness, and conscientiousness. Each of these traits are further separated into sub-traits.

Neuroticism: anxiety, anger/hostility, depression, self-consciousness, impulsiveness, and vulnerability. 

Extraversion: warmth, assertiveness, gregariousness, activity, excitement seeking, and positive emotions.

Openness to experience: fantasy, aesthetics, feelings, actions, ideas, and values.

Agreeableness: trust, straightforwardness, altruism, compliance, modesty, and tender mindedness. 

Conscientiousness: competence, order, dutifulness, achievement striving, self-discipline, and deliberation.

Using this model, when a patient comes in for analysis, she would be rated high or low for each of the factors. The overall pattern (combined with knowledge of whether the individual experiences clinically significant distress) can be used to diagnose a personality disorder. Using the five-factor model, only six of the personality disorders would remain:  borderline, antisocial, schizotypal, narcissistic, obsessive-compulsive, and avoidant. The others (paranoid, schizoid, histrionic, and dependent personality disorders) would be dropped. 

Hopefully much research will go into developing a more empirical approach to diagnosis of personality disorders, for I feel that patients would benefit greatly from treatments that target specific dysfunctional traits instead of a generalized “personality disorder.” 

If you’re interested, there are quite a few Big Five tests on the internet. I just took the Truity test. If you take it, you don’t have to create an account. There’s a “skip” option. My scores were: 

Open to experience: 80%
Conscientiousness: 85%
Extraversion: 57.5%
Agreeableness: 92.5%
Neuroticism: 52.5%

Apparently, a score of 50% is considered “average person.” This test was fun and gives you an idea of what types of questions might be asked with a dimensional approach to diagnosis; however, it was certainly too short and silly to accurately diagnose a personality disorder. I’m surprised I didn’t get a higher score on neuroticism because of my bipolar disorder. Hopefully the test developed by clinical psychologists is much more extensive and precise. 🙂

The Noonday Demon, by Andrew Solomon

The Noonday Demon: An Atlas of Depression,
by Andrew Solomon, narrated by Barrett Whitener 

Noonday Demon is Andrew Solomon’s amazing memoir / history of depression – it’s a must-read for anyone who wants to delve deeply into the causes and effects of depression. Solomon begins with his own journey through several severe depressive episodes. For a broader personal understanding of depression, he intermittently includes stories of “depressives” that he’s interviewed. In his research for this book, Solomon explored many standard therapies for depression (i.e. medicine, psychotherapy, cognitive behavioral therapy, electroconvulsive therapy, etc.); but he also explored some very atypical therapies such as an African ritual in which he lay naked and covered in goat blood while people danced around him with a dead chicken. (He actually found it very cathartic.) 


He followed his personal journey with epidemiology, biological causes, and historical development of depression. 

One subject that I found particularly interesting was when he discussed children of depressed mothers. Solomon claimed that such children are sadder, have lower IQ, more anxiety, and poor social skills. He said that it is often more beneficial to the child to treat the mother instead of the child. 

Solomon made me cringe when he suggested that people who talk about suicide are more likely to commit suicide; therefore, crisis hotlines may actually be promoting suicide rather than preventing it. I’d rather not believe this, since I volunteer for a suicide hotline, though this information does match what Butcher’s Abnormal Psychology textbook claims in chapter 7: that research shows no evidence that crisis hotlines reduce the rate of suicide. However, I’m going to stubbornly continue my work at the crisis hotline, because I can’t possibly think that I’m doing any harm. And I know that most of the people I talk to feel better after the conversation.

Solomon shared a story about a suicidal octopus who was a retired circus performer. Apparently, this octopus kept trying to do its tricks, but was no longer receiving positive reinforcement. The octopus began to fade in color (a sign of stress) and stopped eating. After several months it performed its tricks one last time and then pecked itself to death. Although this was a moving anecdote suggesting that depression can occur in animals as well, I find it a little fishy. After all, anyone who was paying such close attention to the octopus to notice its change of color, appetite loss, and melodramatic last-show would certainly have tried to alleviate the octopus’ suffering. 

Solomon’s history of depression was also quite fascinating. He pointed out that in the late 16th century it was in vogue to be melancholic, and that people would pretend to be depressed – loafing around on couches and saying melodramatic things – in order to appear intellectual. 

Solomon suggested that depression might have evolved in hunter-gatherers in order to promote an appropriate social hierarchy. That early humans became depressed because they were at the bottom of the hierarchy – or after they had challenged the leader and lost. This depression helped them to stay where they belonged in the hierarchy and to discourage them from re-challenging the leader. 

Depression may have had an evolutionary advantage at one time, but it has now lost that purpose. It now manifests for other, less suitable, reasons. Solomon suggests that one reason it is so prevalent these days is our increased choices. Hunter-gatherers didn’t have to stand in a grocery store looking at all the different types of food to eat. They ate whatever came their way. They didn’t have an uncountable number of potential mates, they had only a few. Thus they weren’t plagued by the notion that they may have chosen the wrongly. 

Although the hierarchy-stress hypothesis fits well with Robert Sapolsky’s findings about baboons (I’m currently listening to a set of lectures by Sapolsky and will review soon), I feel a little bit of skepticism about the choice hypothesis. I think there are a lot of reasons we experience stress – choice might be one of them, but it’s not the main factor. 

I found this book fascinating. Solomon did a great job of inserting little vignettes of his own story or stories of people he interviewed into his more intellectual portions of the book, so that the material never became dry despite its length. Solomon came up with so many interesting points that I was always interested in what he would say next. His own story was touching. His facts seemed very well-researched. In short, it was simply an amazing book.

4.5 stars for incredible research, ability to keep up interest,
and generally good writing style.

My Year in Nonfiction – Nonfiction November 2015

This month I will be participating in Nonfiction November, hosted by Doing Dewey, Sophisticated Dorkiness, I’m Lost in Books, and Regular Rumination. In this event, people will be reading and blogging about nonfiction. The event kick-off question is hosted by Sophisticated Dorkiness. 

To date this year, I have read or listened to 51 books, 13 of which were nonfiction (unless you count the Epic of Gilgamesh, of which I’ve read three different translations – hopefully to be reviewed on Friday). So approximately a quarter of my books were nonfiction. 



My favorite nonfiction book of the year would have to be Severed, by Frances Larson. Although all of these books were fantastic , I guess that’s the one that really stands out to me. 


The nonfiction book (of these) that I have recommended the most is Being Mortal, by Atul Gawande. This is actually the book that inspired me to give up my fruitless job search and go back to school to be a physician’s assistant. Of course, I’m far from PA school at the moment, but I’m working my way there slowly. Unfortunately, this book was read before I decided to start up a new blog. So there’s no review.

One topic in nonfiction that I would like to read more of is social justice – especially in terms of mass incarceration, and the horrifying ratios of mentally ill or minority inmates compared to “normal” or white inmates. I have a bunch of these books on my wishlist, so hopefully I’ll get to them soon.

One thing I hope to get out of participating in Nonfiction November is to catch up on my nonfiction reviews. It’s also nice to meet other intelligent people who review books other than YA. Don’t get me wrong – I love my YA. But there are a glut of blogs out there that only review YA, and it’s hard to sift through them to find the more intellectual people. 

What about you? Do you have any nonfiction planned for this month?

Depression – an overview

Depression is a surprisingly common mental health issue, affecting 17% of Americans at some point throughout their lifetimes. Depressions almost always are a result of a stressful life event, though not all of these depressions are severe enough or long enough in duration to be considered a mood disorder. 


For instance, grief or bereavement often occurs when an individual has lost a loved one. Grievers tend to experience numbness and disbelief, yearning and searching for the lost person before acceptance that he is gone, disorganization and despair as realization is reached, and finally acceptance and reorganization of life. The DSM-IV had a bereavement exclusion for major depressive disorder (MDD): a person might not receive a diagnosis for MDD if he had experienced a major loss in the last two months. However, in a controversial move, this exclusion principle was left out of the DSM-5, allowing clinicians to diagnosis MDD soon after a major loss. 

There are a surprising number of types of depression – many of them are well-known but not generally considered when we think about depression. For instance, postpartum depression is a negative mood response to the birth of a child. Feelings of changeable mood, crying easily, sadness, and irritability occur in 50 to 70 percent of women within 10 days of the birth. These symptoms generally subside on their own. 

Another type of DSM-5 diagnosable depression is premenstrual dysphoric disorder. (That’s right. PMS.) In order to get this diagnosis, one of four symptoms must occur a week before onset of menses, and disappear within the first couple of days after onset. Those four symptoms are: mood swings, irritability or anger, depressed mood or self-deprecation, and anxiety or being “on edge.” 

MDD is characterized by persistent symptoms that occur most of the day, every day for at least two weeks. The patient must either have a depressed mood or a loss of interest or pleasure (anhedonia). There is also a list of 7 symptoms, of which the patient must have 4: significant weight change, hypersomnia or insomnia, psychomotor agitation or retardation, fatigue, inability to concentrate, and recurrent thoughts of death. Untreated, these symptoms generally last 6 to 9 months. 

There are several types of MDD. The specifiers are: “with melancholic features,” “with psychotic features,” “with atypical features,” “with catatonic features,” and “with seasonal pattern.” 

The melancholic patient awakens early in the morning, has depression that is worse in the morning, exhibits psychomotor agitation or retardation, loss of appetite, and/or excessive guilt. 

Psychotic features are delusions or hallucinations that are “mood congruent” (in other words, they tend to be a very depressing psychotic experiences). One example is the belief that one’s internal organs have completely deteriorated, leading to the depression. Patients with psychotic features generally experience extreme guilt and feelings that they deserve depression as punishment.

Atypical features include more mood fluctuations than a person with MDD would usually experience. The patient’s spirits might temporarily lift at a positive event. Other atypical features are increase in appetite, hypersomnia, arms and legs feel as heavy as lead, and being acutely sensitive to interpersonal reaction. 

I find the description of atypical features to be interesting because in the times that I have experienced severe depression, I have experienced all of these symptoms. But apparently people with bipolar disorder tend to have atypical features to their depressive episodes. In fact, a person should not be diagnosed with MDD if they have ever experienced a manic or hypomanic episode, as I have. Another interesting difference between MDD and bipolar disorder is that those with bipolar tend to have much deeper depression than those with “unipolar” depression.

Catatonic depressives experience extreme psychomotor retardation often to the point of complete immobility. They often stop talking as well. I have an aunt who experienced these symptoms for weeks at a time during her teenage years. Apparently, she would just sit at the kitchen table all day, every day. Not moving, not talking, just staring. I’ve asked my dad “didn’t she eat or go to the bathroom or to bed?” He just answers “I don’t know. I never saw her doing those things.” 

In order to be diagnosed with a seasonal pattern, you must have experienced two or more depressive episodes in the past two years that occurred at the same time of year, usually fall or winter, with a full remission at the same time of year, usually spring or summer. Sometimes the seasons can be switched – these patients tend not to get as much sympathy as those who get depressed in the winter. To get this diagnosis, non-seasonal depression must not have occurred in this 2 year period. 

When depression occurs almost every day for most of the day for more than two years, the patient is generally diagnosed with persistent depressive disorder. “Normal” moods may occur, but they generally only last for a few days. This depression contains many of the same characteristics of MDD, though they are not as severe. Persistent depressive disorder generally lasts for 4-5 years, but can last longer than 20 years. It often starts during adolescence. This disorder is quite common, occurring with a lifetime prevalence of 2.5-6% in Americans. 

Depression has been attributed to many biological causes. There is a genetic factor – people with family members who have MDD are more likely to develop MDD themselves. The serotonin-transporter gene, which is responsible for the uptake of serotonin in the brain, has a heritable mutation which makes depression much more likely. An imbalance of the neurotransmitters norepinephrine or serotonin is strongly associated with depression, and most anti-depressant medications target these neurotransmitters. 





Another biological cause can be a dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. In response to a perceived threat, norepinephrine signals the hypothalamus to release a signal which eventually leads to release of the stress hormone cortisol from the adrenal gland. Cortisol is not harmful for short periods of time, but long-term it can promote hypertension, heart disease, and obesity. It is hypothesized that during MDD, the signal stimulating cortisol release is continuously present in the system, or the feedback inhibition mechanism, which tells the adrenal gland that it should stop releasing cortisol, is not functional. The HPA axis is related to the stress response, which explains the onset of depression after stressful life events, and also explains the concurrence of depression with anxiety. 

There are several theories about psychological causes of depression. In 1967, Aaron Beck proposed the cognitive theory of depression – which led to the development of cognitive behavioral therapy (discussed in my post Contemporary viewpoints on treating mental illness – psychology). Beck proposed that before experiencing depression, a person experienced dysfunctional thinking – these thoughts could be about oneself, about the world, or about one’s future. Dysfunctional thinking may include: 1) all-or-none thinking, for example someone thinks he must get 100% on a test or he is a complete loser; 2) selective abstraction, which includes a tendency to focus on one negative event even if surrounded by positive events; and 3) arbitrary inference in which the individual jumps to a conclusion based on little to no evidence. (Examples of these are given in my previous post.) Although research shows that this dysfunctional thinking occurs during depression, research leaves it unclear whether dysfunctional thinking occurs prior to depression, suggesting that such thinking might not be the cause of depression, as theorized by Beck.

There are also the hopelessness and helplessness theories of the psychological causes of depression. In these, the individual might feel incredibly pessimistic about the future, or incapable of having any impact on himself or his environment. A final theory is the ruminative theory, in which a person’s tendency to roll negative thoughts over-and-over in her head leads to depression. Women tend to ruminate more than men, and they also are more likely to experience depression than men. But when a study controls for rumination, the sex difference disappears, suggesting that rumination has a strong impact on depression.

October 2015 Review

Photo of the month: pumpkin selfie

Wow. This was quite the month. Most of it is fuzzy due to my bipolar mixed state which gobbled up most of my conscious activity. But I’m starting to emerge, thankfully.

At some point, I decided to choose this crying piggy bank as my monthly topper – probably because I spent a huge chunk of money on my new contact lenses, but it may also have been because the picture’s really darned cute. I’ve decided to include it now, even though it doesn’t summarize the month as well as I’d expected at one foggy moment in a long foggy month.



I’d say more about my month, but I’m a bit foggy. 🙂 So I’ll let the posts and pictures say the rest:

 I’m currently reading or listening to:

Book & Movie Reviews


Already started this series. Thought it would be a nice addition to A More Diverse Universe, The Halloween Reading Challenge, and R. I. P. X
This has been collecting virtual dust in my Audible library. Thought it would be a nice addition to The Halloween Reading Challenge, and R. I. P. X
I started this a long time ago for my bookclub and wasn’t able to finish it on time. Figured now was a good time since the review would fit in well with A More Diverse Universe, The Halloween Reading Challenge, and R. I. P. X


Read this so that I could discuss it with my Abnormal Psychology Prof


Read this classic vampire story for 
The Halloween Reading Challenge, and R. I. P. X and The Classics Club
I read this to supplement my study of The Epic of Gilgamesh.
This is a classic text discussing the theories about the relationship of the flood myths in Gilgamesh Epic and the Old Testament.
I was supposed to finish this 12-part series for my bookclub a while back, but I only got through 7. I’m slowly trying to finish the series because it is rather interesting. 


This book has been hanging out in my Audible library for quite a long time.
In my efforts to decrease my TBR pile, I read it. Thought it would fit in nicely with
The Halloween Reading Challenge, and R. I. P. X
How could I resist? 
Thought it would fit in nicely with The Halloween Reading Challenge, and R. I. P. X
This is my RL book club pick for November
I actually didn’t finish this one. I got about 3 hours into the 14 hour book.
I was interested in what Greenberg had to say about the problems with the DSM classification system (for there are many)…and he had some good ones
But with his bashing of psychiatry he promotes stigma and ignorance of mental health by encouraging the people who believe that mental illness either doesn’t exist (“it’s all in their heads”) or is caused by a weakness of character.
Although interested in what he had to say, the book made me so angry that I couldn’t listen anymore.
Picked this up off the Audible New Release section.
Figured it’d be one last hoorah for the Halloween season.

Movies/Shows watched:

Watched this with my boyfriend. Thought it would be a nice addition to The Halloween Reading Challenge, and R. I. P. X

Watched this horror flick with my boyfriend, but since I only gave it 3 snowflakes, I decided not to review it. 


Thought it would be fun to watch the movies after reading the book.
This is the original Swedish version of the movie
This is the American remake of the Swedish film.
I expected it to be a remake of the Swedish book, but it wasn’t.
Watched it after reading the book.
I like to compare different adaptations.
Watched this while I was giving platelets. Wow. It was pretty amazing. 
Went to this in the theater with my sister and her son.
While not as hilarious as the first, it was a fantastic sequel.

The Tide, by Anthony J. Melchiorri

The Tide, by Anthony J Melchiorri, narrated by Ryan Kennard Burke
Captain Dominic Holland (Dom) is head of a covert operations team which investigates bioterrorism. As he and his team check out some suspicious activity on what was believed to be an abandoned oil rig, bone-armored mutant men begin to wash up on shores of countries around the world. Soon, citizens become crazed – brutally attacking and devouring people. Dom’s team rushes to find a cure to the bioweapon, as civilization crashes around them. 


I found this book in the new releases in Audible and thought I’d try it out. The genre is basically bioweapon zombie apocalypse, but the “zombies” aren’t actually zombies. They are living humans who develop bony armor around their bodies and get brain activation of unthinking violence. It was a fast-paced, high-action book. The science was very reasonable – clearly Melchiorri did his research – which I like to see in biotech books (otherwise I tend to roll my eyes and criticize every little mistake). Yes, the race for a cure moved along much too fast to be realistic, but that’s the nature of the genre, not a problem with Melchiorri’s writing. Nobody wants to read a book with the pacing of real life, after all. 🙂 

I think this book will be quite enjoyable to anyone who likes biotech apocalypse thrillers, especially those who enjoyed Jonathan Maberry’s Patient Zero. But beware, it is the first in a series, and the story just cuts off at the end – there’s not a satisfying conclusion. Luckily, Melchiorri is releasing the second one hot on the heels of the first, so this may not be an issue for many readers. 

I decided to give this book four stars despite the fact that there wasn’t a satisfying ending. The science was excellent and it was just what a biotech thriller should be. 

Let Me In, by John Ajvide Lindqvist

Let Me In, by John Ajvide Lindqvist, narrated by Steven Pacey

Oskar, a 12-year-old boy, is bullied by his schoolmates. He spends his time fantasizing about revenge and stabbing trees with a knife. He obsesses about violent crimes, keeping a notebook of newspaper clippings. One day, a strange girl and her father move in next door. She seems quite unaware of social norms and completely immune to getting cold. Her father and she argue loudly and frequently, which Oskar can hear through his wall. Despite the fact that she tells him they can’t be friends, Eli and Oskar soon form a bond. She encourages him to stand up to his bullies, and he starts growing in self-confidence. But strange murders are suddenly occurring in his neighborhood, and Oskar begins to suspect that Eli is more than he thought she was. 

I have been interested in reading this book after reading a fascinating short story of his a few years ago. This book did not disappoint. It was eerie and consuming. It was also very gruesome, and it has some graphic child-sexual-abuse scenes, so beware. Luckily, I had read reviews of this book beforehand and already knew about the child abuse, so I was not quite as repulsed by it. However, this book lost an entire star because of the child-sexual-abuse, which didn’t appear at all in the movies and wasn’t absolutely necessary. The child abuse did help develop the character of Eli’s father as a disgusting and pathetic failure, but I think both attributes could have been manged in other ways. Or, at least, without the graphic scenes.

In general, I am pleased with Lindqvist’s style – it is mysterious and flows well. The characters were well-drawn and believable (in a there-be-vampires sort of way). There dark, dreary mood was set early in the book and retained steadily throughout. There was nothing particularly original about Lindqvist’s vampire, though Eli had some original personality traits and circumstances. Also, I’ve seen this book described as a romance, and I don’t agree with that. Yes, Oskar asked Eli to “go steady,” but that was about it. I mean, he was 12, and those feelings were very naive and not pronounced. This was a book about friendship, not romance.

Overall, I was pleased with the book and would read another by Lindqvist, though I’ll probably wait before I can get through another that has sexual abuse in it. The audiobook was well-read – the voices were distinguishable and the pacing was quite reasonable.
3.5 stars for flow, eeriness, mystery – star lost for child sexual abuse



Hoarding and Body Dysmorphic Disorders


Obsessive compulsive disorder (discussed in a previous post) is grouped in a DSM-5 category called “obsessive compulsive and related disorders.” Other disorders included in this category are hoarding, body dysmorphic, trichotillomania (hair picking), and excoriation (skin picking) disorders. 

Upon publication of the DSM-5, there were a lot of ignorant people laughing at the “new” disorder “hoarding,” and giving it as an example of how the DSM-5 encourages over-diagnosis of “normal” individuals. Such people do not understand the dire nature of this disorder. An individual with hoarding disorder finds it extremely distressful to discard objects, regardless of their actual value. These objects fill up their living spaces, leading to impairment of the individual’s ability to live a healthy, functional life. 


Hoarding has recently reached the popular eye due to TV shows like A&E’s Hoarders or TLC’s Hoarding: Buried Alive. I haven’t watched either of these shows, so I don’t know if they are a good representative of the dangers of hoarding. But I can give examples of such dangers:

To go along with my Adrian Monk theme in my OCD post, Adrian’s brother Ambrose Monk is an extremely agoraphobic hoarder. In the episode Mr. Monk and the Three Pies, Ambrose’s house is set on fire, and he is unable to exit the house – partly due to the lack of safe pathways through his piles of newspapers. 

If you like real-life examples, I have an acquaintance with hoarding disorder. She fell in her home and was unable to get up due to the huge piles of junk surrounding her. She lay there three days before someone found her. Luckily, she was holding a jug of juice when she fell, so she survived surprisingly well during this time. 

Obsessive hoarders tend not to respond to the same types of medications or therapies as people with OCD, and their brain activation patterns are different than those recorded in OCD patients. Therefore, it is possible the two disorders might not be as strongly related as categorized in the DSM-5.

People with body dysmorphic disorder (BDD) become obsessed with one or more body parts that they perceive as hideous or deformed. When people with BDD look in the mirror, they often see a defect that is not present, such as the woman above seeing herself as fat when she is actually thin. Such people are often self-conscious about this perceived defect, and believe that everyone around them look down on them for their ugly appearance. People with BDD might spend hours every day looking in a mirror obsessing about their perceived defect, or they might compulsively avoid mirrors altogether. BDD patients often avoid social situations, and sometimes they stop leaving their house altogether. It’s possible, even, that they might have so many plastic surgeries that their nose dies (rumored to have happened to a certain deceased celebrity). 
One example you might immediately think of (especially since it is pictured above) is people with anorexia nervosa. However, anorexia is not always a form of BDD. Many anorexics are emaciated and are pleased with their appearance. Some, however, are emaciated and see themselves as fat when they look in the mirror. These are the type with BDD. A long time ago, I remember reading about a study in which a tight-fitting full-body suit was worn by BDD-related anorexics. The tightness of the suit allowed the subjects to change thier proprioceptive perception of their body types. Because they could feel how thin they were, they began to perceive themselves as thin. I’m pretty sure I read about this study in Sandra Blakeslee’s book The Body Has a Mind of Its Own: How Body Maps in Your Brain Help You Do (Almost) Everything Better. 

More mainstream treatments for BDD include SSRI’s and a form of cognitive behavioral therapy in which the subject is made to wear clothing or makeup that accentuates the “defect” rather than disguising it. The subject is also told to not look in a mirror, even when they feel compelled to.
